The Industrial feeder is not so lengthy but still needs margin for cold load restoration & pick up, we may go for very inverse characterstics curve ;
so as to quick clearances of close in faults owing to fact that the close in spans of 11 Kv feeders always remain pre- occupied with bamboo trees.

The Industrial feeder is not so lengthy but still needs margin for cold load restoration & pick up, we may go for very inverse characterstics curve ;
so as to quick clearances of close in faults owing to fact that the close in spans of 11 Kv feeders always remain pre- occupied with bamboo trees.
